Summa Theologica

By Thomas Aquinas

OF VENIAL SIN IN ITSELF (SIX ARTICLES)

We must now consider venial sin in itself, and under this head there are six points of inquiry:

(1) Whether venial sin causes a stain in the soul?

(2) Of the different kinds of venial sin, as denoted by "wood," "hay," "stubble" (1 Cor.3:12);

(3) Whether man could sin venially in the state of innocence?

(4) Whether a good or a wicked angel can sin venially?

(5) Whether the movements of unbelievers are venial sins?

(6) Whether venial sin can be in a man with original sin alone?
